Millions of rats living on the NYC subway tracks don't faze New Yorkers in the least. But recently, the rats have started venturing onto slumbering passengers. And now: alarming video evidence shows that rats consider themselves normal subway riders.

Notice how the presence of the rat on this R train car (filmed just two days ago) causes the passengers to scamper onto seats and raise their legs off of the floor, as if rats were unable to climb walls or, more likely, to drop down onto your head unannounced from a small crack in the ceiling. The rat, by contrast, calmly rides along and gets off the train at the next stop.

That rat revenue is an important part of the MTA's latest budget. Get used to it.
